LX steamcmd dumps core

[cneira]

When trying to run steamcmd in a lx branded zone it segfaults when it tries to validate a game ( the game seems to be downloaded as the 100% implies but has not been written to the steam location yet)

How to reproduce

Install steamcmd in an ubuntu lxbranded zone ( I have not tested with other image)

https://developer.valvesoftware.com/wiki/SteamCMD#Ubuntu

Then try to install a game , in this case ark:

 steamcmd +force_install_dir arkserver  +login anonymous +app_update 376030 +quit

When the download reaches 100% it will dump core.

arkserver@ca47b8b6-5bde-466a-b5ff-6ddb472d15b2:~$ steamcmd +force_install_dir arkserver  +login anonymous +app_update 376030 +quit

If I run the command steamcmd interactively there is more info on the coredump
